A government advisory panel on nonfinancial firms' entry into the banking and insurance sectors issued a final report Thursday that was slightly watered down from an interim report.

In the new report, the Financial System Council altered two regulations that had come under criticism. One would require parties planning to buy 20 percent or more of a bank's or insurer's outstanding shares to undergo background inspections.

Authorities could block a deal if they are not satisfied with the background check.
